Answer:

A principal quantum number refers to the energy level of the orbital.

Explanation:

A principal quantum number refers to the energy level of the orbital, the first level being the one with the lowest energy. This orbital refers to the average distance of the electron to the nucleus, this mean when the principal quantum number increases the energy of that orbital increases too but the probability of finding the electron near the nucleus decreases.

This quantum number can take  positive integers from 1 to 7

<span> this represents the relative overall energy of each orbital, and the energy of each orbital increases as the distance from the nucleus increases</span>

Explain why we use 1/12 in finding atomic mass unit ?​
Nat2105 [25]

Answer:

The u (amu is the old unit name) is 1/12 of the weight of an 12C atom. The way the u is chosen ensures that all core and atom masses are multiples of 1(±0.1) u.

Explanation:

Further explanation if needed...

Carbon 12 was chosen because the chemical atomic weights based on C12 are almost identical to the chemical atomic weights based on the natural mix of oxygen. Simply because the atomic mass is defined as 1/12 of the mass of 12C. Others isotopes of carbon (13C mostly, with an abundance of 1.1% approximately) account for an average atomic mass slightly above 12.
